DEVELOPMENT OF A PLANNING SUPPORT SYSTEM FOR BARRIER-FREE STREET NETWORK

抄録

In aging society, transportation infrastructure should be more accessible and safe for all people to encourage a participation to a society. However, an existing method and its support system for designing a barrier-free environment considering a street network structure is insufficient today. This paper presents a planning support system for designing a barrier-free street network in the central part of Morioka city. It is integrated by a geographic information system that consists of a database, a calculation program and a visual interface. The database contains the data of obstacles distributed over the street network. The data are collected from a field survey based on the guideline for barrier-free road improvement published in 2003. A route between an origin and a destination is restricted for a pedestrian because of the obstacles. The system gives us a route and its travel time for evaluating an achievement level of a barrier-free on the street network.
